Balancing & Interchange
Keep generation and scheduled interchange matched to load second by second within the balancing area, hold frequency within limits and keep enough reserves to recover from the loss of a large unit.
- Balancing Authority
- Frequency Control
- Load-Frequency Control
In scope
- Automatic generation control and area control error
- Scheduled interchange with neighboring balancing areas
- Operating and regulating reserves, and directing load relief in energy emergencies
Out of scope
- Plant output setpoints and unit commitment (see BC-1540.10)
- Energy schedules nominated as a market participant (see BC-1570.20.20)

- BC-1590.20.10Automatic Generation ControlAdjust the output of participating generators every few seconds so area control error and system frequency stay within limits.
- BC-1590.20.20Interchange SchedulingAgree, confirm and implement scheduled transfers of energy with neighboring balancing areas and check them against transmission limits.
- BC-1590.20.30Operating Reserve MonitoringKeep enough contingency and regulating reserves online, and deploy them to restore balance after a generator or line trips.
